Accounting Policies [Abstract]
Summary of significant accounting policies	Summary of significant accounting policies Business Amgen Inc. (including its subsidiaries, referred to as “Amgen,” “the Company,” “we,” “our” or “us”) is a global biotechnology pioneer that discovers, develops, manufactures and delivers innovative human therapeutics. We operate in one business segment: human therapeutics. Basis of presentation The financial information for the three and six months ended June 30, 2023 and 2022, is unaudited but includes all adjustments (consisting of only normal, recurring adjustments unless otherwise indicated), which Amgen considers necessary for a fair presentation of its condensed consolidated results of operations for those periods. Interim results are not necessarily indicative of results for the full fiscal year. The condensed consolidated financial statements should be read in conjunction with our consolidated financial statements and the notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2022, and with our condensed consolidated financial statements and the notes thereto contained in our Quarterly Report on Form 10-Q for the period ended March 31, 2023. Principles of consolidation The condensed consolidated financial statements include the accounts of Amgen as well as its majority-owned subsidiaries. In determining whether we are the primary beneficiary of a variable interest entity, we consider whether we have both the power to direct activities of the entity that most significantly impact the entity’s economic performance and the obligation to absorb losses of or the right to receive benefits from the entity that could potentially be significant to that entity. We do not have any significant interests in any variable interest entities of which we are the primary beneficiary. All material intercompany transactions and balances have been eliminated in consolidation. Use of estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results may differ from those estimates. Property, plant and equipment, net Property, plant and equipment is recorded at historical cost, net of accumulated depreciation and amortization, of $9.5 billion and $9.3 billion as of June 30, 2023 and December 31, 2022, respectively. Recent accounting pronouncements No new accounting pronouncements were issued or adopted for the six months ended June 30, 2023, that materially impacted the Company.

Restructuring

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring In the first quarter of 2023, we initiated a restructuring plan to enhance continued innovation, including investments in first-in-class medicines, while improving our cost structure. As part of the plan, we are reallocating resources to the areas of the business that will enable long-term growth. We estimate that we will incur $300 million to $400 million of pretax charges in 2023 in connection with our restructuring plan, including (i) separation and other headcount-related costs with respect to staff reductions and (ii) asset-related charges that consist primarily of asset impairments, accelerated depreciation and other related costs resulting from rationalization of our geographic footprint. The following tables summarize recorded charges related to the restructuring plan by type of activity and the locations recognized within the Condensed Consolidated Statements of Income (in millions): Three months ended June 30, 2023 Separation costs Asset impairments and other charges Total Cost of sales $ — $ — $ — Research and development — 17 17 Other 25 — 25 Total $ 25 $ 17 $ 42 Six months ended June 30, 2023 Separation costs Asset impairments and other charges Total Cost of sales $ — $ 35 $ 35 Research and development — 17 17 Other 166 3 169 Total $ 166 $ 55 $ 221 As of June 30, 2023, total restructuring liability decreased to $82 million primarily due to payments related to separation costs. The total restructuring liability was included in Accrued liabilities in the Condensed Consolidated Balance Sheets.

Business Combination and Asset Acquisition [Abstract]
Acquisitions and divestitures	Acquisitions and divestitures Proposed acquisition of Horizon Therapeutics plc On December 12, 2022, we announced that we had entered into a transaction agreement under which Amgen will acquire all shares of Horizon for $116.50 per share in cash for a transaction equity value of approximately $27.8 billion. Horizon is a global biotechnology company headquartered in Dublin, Ireland and is focused on the discovery, development and commercialization of medicines that address critical needs for people impacted by rare, autoimmune and severe inflammatory diseases. Horizon has 12 marketed medicines and a pipeline with more than 20 development programs. In May 2023, the FTC filed a complaint in the U.S. District Court for the Northern District of Illinois seeking a temporary restraining order and preliminary injunction enjoining our proposed acquisition of Horizon. See Note 14, Contingencies and commitments. In connection with our proposed acquisition of Horizon, we entered into several debt and financing arrangements. See Note 10, Financing arrangements. Acquisition of ChemoCentryx, Inc. On October 20, 2022, we acquired all of the outstanding stock of ChemoCentryx, a publicly traded biotechnology company focused on orally administered therapeutics to treat autoimmune diseases, inflammatory disorders and cancer, for $52.00 per share in cash, representing a total consideration of $3.9 billion. The acquisition, which was accounted for as a business combination, includes TAVNEOS, an orally administered selective complement 5a receptor inhibitor that was approved by the FDA in October 2021 as an adjunctive therapy for adults with severe active anti-neutrophil cytoplasmic autoantibody-associated vasculitis (ANCA-associated vasculitis). TAVNEOS is commercialized by us in the United States; for markets outside the United States, TAVNEOS is commercialized by a collaboration partner, and Amgen is entitled to royalties and milestones based on future sales of the product. Upon its acquisition, ChemoCentryx became a wholly owned subsidiary of Amgen, and its operations became included in our consolidated financial statements commencing on the acquisition date. Measurement period adjustments during the six months ended June 30, 2023, included changes in the purchase price allocation and total consideration, resulting in a net decrease of approximately $4 million to goodwill. The measurement period adjustments resulted primarily from valuation inputs pertaining to the TAVNEOS intangible assets and adjustments to vendor payables based on facts and circumstances that existed as of the acquisition date and did not result from events subsequent to the acquisition date. The adjustments did not have a significant impact on Amgen’s results of operations during the six months ended June 30, 2023, and would not have had a significant impact on prior-period results if the adjustments had been made as of the acquisition date. The following table summarizes the total consideration and allocated acquisition date fair values of assets acquired and liabilities assumed, inclusive of measurement period adjustments (in millions): Amounts Cash and cash equivalents $ 86 Marketable securities 235 Inventories 41 Finite-lived intangible assets — developed-product-technology rights 3,499 Goodwill 663 Other liabilities, net (83) Deferred tax liability, net (516) Total assets acquired, net $ 3,925 The $3.9 billion total consideration consisted of (i) a $3.7 billion cash payment to outstanding common stockholders of ChemoCentryx and (ii) a $181 million cash payment to equity award holders of ChemoCentryx for services rendered prior to the acquisition date of October 20, 2022, under the ChemoCentryx equity award plans. The developed-product-technology rights acquired relates to TAVNEOS, which is approved in the United States and the EU for ANCA-associated vasculitis. The estimated fair values of $3.5 billion were determined by using a multi-period excess earnings income approach that discounts expected future cash flows to present value by applying a discount rate that represents the estimated rate that market participants would use to value the intangible assets. The developed-product-technology rights are being amortized on a straight-line basis over a weighted-average period of approximately 11 years using the straight-line method. The estimated fair value of the acquired inventory of $41 million was determined using the comparative sales method, which uses actual or expected selling prices of inventory as the base amount to which adjustments for selling effort and a profit on the buyer’s effort are applied. The inventory fair value adjustment is being amortized as inventory turns over, which we estimate to be approximately 13 months. A net deferred tax liability of $516 million was recognized on the temporary differences related to the book bases and tax bases of the acquired identifiable assets and assumed liabilities, primarily driven by the intangible assets acquired. The excess of the acquisition date consideration over the fair values assigned to the assets acquired and the liabilities assumed of $663 million was recorded as goodwill, which is not deductible for tax purposes. The goodwill value is primarily attributable to the expected synergies from the TAVNEOS asset. Our accounting for this acquisition is preliminary and will be finalized upon completion of our analysis to determine the acquisition date fair values of certain assets acquired, liabilities assumed and tax-related items as we obtain additional information during the measurement period of up to one year from the acquisition date. Divestiture of Gensenta İlaç Sanayi ve Ticaret A.Ş. On November 2, 2022, we sold our shares in Gensenta, a subsidiary in Turkey, to Eczacıbaşı for net cash proceeds of approximately $130 million. The transaction was accounted for as a sale of a business and did not meet the criteria to be classified as discontinued operations. Upon closing of this transaction, net assets related to Gensenta of $86 million were divested, and during the year ended December 31, 2022, we recognized a loss on divestiture of $567 million recorded in Other operating expenses in the Consolidated Statements of Income, primarily due to the reclassification of $615 million of cumulative foreign currency translation losses from AOCI into earnings.

The increase in our effective tax rate for the three months ended June 30, 2023, was primarily due to the new Puerto Rico income tax beginning in 2023, partially offset by the current period change in the fair value of our equity investments and net favorable items. The increase in our effective tax rate for the six months ended June 30, 2023, was primarily due to the new Puerto Rico income tax beginning in 2023, current year change in the fair value of our equity investments and an increase in interest expense on tax reserves, partially offset by net favorable items. The effective tax rates differ from the federal statutory rate primarily as a result of foreign earnings from the Company’s operations conducted in Puerto Rico, a territory of the United States treated as a foreign jurisdiction for U.S. tax purposes, that are currently subject to a tax incentive grant through 2050. In addition, the Company’s operations conducted in Singapore are subject to a tax incentive grant through 2036. These foreign earnings are also subject to U.S. tax at a reduced rate of 10.5%. We are no longer subject to a 4% excise tax in the U.S. territory of Puerto Rico on the gross intercompany purchase price of goods and services from our manufacturer in Puerto Rico. As of January 1, 2023, we qualify for the alternative income tax rate on industrial development income of our Puerto Rico affiliate. In the United States, this income tax qualifies for foreign tax credits. Both this income tax and the associated foreign tax credits are generally recognized in our provision for income taxes. We account for the 2022 excise tax that was capitalized in Inventories as an expense in Cost of sales when the related products are sold in 2023, and a foreign tax credit will not be recognized in 2023 with respect to the excise tax. One or more of our legal entities file income tax returns in the U.S. federal jurisdiction, various U.S. state jurisdictions and certain foreign jurisdictions. Our income tax returns are routinely examined by tax authorities in those jurisdictions. Significant disputes can and have arisen with tax authorities involving issues regarding the timing and amount of deductions, the use of tax credits and allocations of income and expenses among various tax jurisdictions because of differing interpretations of tax laws, regulations and relevant facts. Tax authorities, including the IRS, are becoming more aggressive and are particularly focused on such matters. In 2017, we received an RAR and a modified RAR from the IRS for the years 2010–2012, proposing significant adjustments that primarily relate to the allocation of profits between certain of our entities in the United States and the U.S. territory of Puerto Rico. We disagreed with the proposed adjustments and calculations and pursued resolution with the IRS appeals office but were unable to reach resolution. In July 2021, we filed a petition in the U.S. Tax Court to contest two duplicate Statutory Notices of Deficiency (Notices) for the years 2010–2012 that we received in May and July 2021, which seek to increase our U.S. taxable income for the years 2010–2012 by an amount that would result in additional federal tax of approximately $3.6 billion plus interest. Any additional tax that could be imposed for the years 2010–2012 would be reduced by up to approximately $900 million of repatriation tax previously accrued on our foreign earnings. In 2020, we received an RAR and a modified RAR from the IRS for the years 2013–2015, also proposing significant adjustments that primarily relate to the allocation of profits between certain of our entities in the United States and the U.S. territory of Puerto Rico similar to those proposed for the years 2010–2012. We disagreed with the proposed adjustments and calculations and pursued resolution with the IRS appeals office but were unable to reach resolution. In July 2022, we filed a petition in the U.S. Tax Court to contest a Notice for the years 2013–2015 that we previously reported receiving in April 2022 that seeks to increase our U.S. taxable income for the years 2013–2015 by an amount that would result in additional federal tax of approximately $5.1 billion, plus interest. In addition, the Notice asserts penalties of approximately $2.0 billion. Any additional tax that could be imposed for the years 2013–2015 would be reduced by up to approximately $2.2 billion of repatriation tax previously accrued on our foreign earnings. We firmly believe that the IRS positions set forth in the 2010–2012 and 2013–2015 Notices are without merit. We are contesting the 2010–2012 and 2013–2015 Notices through the judicial process. The two cases were consolidated in the U.S. Tax Court on December 19, 2022. On February 10, 2023, the U.S. Tax Court entered an order setting a trial date of November 4, 2024. We are currently under examination by the IRS for the years 2016–2018 with respect to issues similar to those for the 2010 through 2015 period. In addition, we are under examination by a number of state and foreign tax jurisdictions. Final resolution of these complex matters is not likely within the next 12 months. We continue to believe our accrual for income tax liabilities is appropriate based on past experience, interpretations of tax law, application of the tax law to our facts and judgments about potential actions by tax authorities; however, due to the complexity of the provision for income taxes and uncertain resolution of these matters, the ultimate outcome of any tax matters may result in payments substantially greater than amounts accrued and could have a material adverse impact on our condensed consolidated financial statements. We are no longer subject to U.S. federal income tax examinations for years ended on or before December 31, 2009. See our Annual Report on Form 10-K for the year ended December 31, 2022, Part I, Item 1A, Risk Factors— The adoption and interpretation of new tax legislation or exposure to additional tax liabilities could affect our profitability, for further discussion.

Earnings Per Share [Abstract]
Earnings per share	Earnings per share The computation of basic EPS is based on the weighted-average number of our common shares outstanding. The computation of diluted EPS is based on the weighted-average number of our common shares outstanding and dilutive potential common shares, which primarily include shares that may be issued under our stock option, restricted stock and performance unit award programs (collectively, dilutive securities), as determined by using the treasury stock method. The computations for basic and diluted EPS were as follows (in millions, except per-share data): Three months ended Six months ended 2023 2022 2023 2022 Income (Numerator): Net income for basic and diluted EPS $ 1,379 $ 1,317 $ 4,220 $ 2,793 Shares (Denominator): Weighted-average shares for basic EPS 535 535 534 541 Effect of dilutive securities 2 2 3 3 Weighted-average shares for diluted EPS 537 537 537 544 Basic EPS $ 2.58 $ 2.46 $ 7.90 $ 5.16 Diluted EPS $ 2.57 $ 2.45 $ 7.86 $ 5.13 For the three and six months ended June 30, 2023 and 2022, the number of antidilutive employee stock-based awards excluded from the computation of diluted EPS was not significant.

Cash and cash equivalents as of June 30, 2023 was $34.2 billion, of which $27.8 billion is anticipated to be used for the proposed acquisition of Horizon. See Note 3, Acquisitions and divestitures. All interest-bearing securities as of June 30, 2023 and December 31, 2022, mature in one year or less. For the three and six months ended June 30, 2023 and 2022, realized gains and losses on interest-bearing securities were not material. Realized gains and losses on interest-bearing securities are recorded in Other (expense) income, net, in the Condensed Consolidated Statements of Income. The cost of securities sold is based on the specific-identification method. The primary objective of our investment portfolio is to maintain safety of principal, prudent levels of liquidity and acceptable levels of risk. Our investment policy limits interest-bearing security investments to certain types of debt and money market instruments issued by institutions with investment-grade credit ratings, and it places restrictions on maturities and concentration by asset class and issuer. Equity securities BeiGene, Ltd. Effective January 30, 2023, we relinquished our right to appoint a director to BeiGene’s Board of Directors. We no longer have the ability to exert significant influence over BeiGene. As a result, in the first quarter of 2023, we began to account for our ownership interest as an equity security with a readily determinable fair value, with changes in fair value recorded in Other (expense) income, net. See Note 12, Fair value measurement. During the three and six months ended June 30, 2023, we recognized an unrealized loss of $705 million and an unrealized gain of $1.2 billion, respectively, recorded in Other (expense) income, net, in our Condensed Consolidated Statements of Income. As of June 30, 2023, the carrying and fair value of our investment in BeiGene was $3.4 billion and was included in Other noncurrent assets in the Condensed Consolidated Balance Sheets. As of December 31, 2022, under the equity method of accounting, the carrying value of our investment in BeiGene was $2.2 billion and was included in Other noncurrent assets in the Condensed Consolidated Balance Sheets, and our ownership percentage was 18.2%. During the three and six months ended June 30, 2022, under the equity method of accounting, our carrying value in BeiGene was adjusted by our share of BeiGene’s net losses of $80 million and $188 million, respectively, and amortization of the basis difference of $48 million and $95 million, respectively, recorded in Other (expense) income, net, in our Condensed Consolidated Statements of Income. Other equity securities Excluding our equity investment in BeiGene, we held investments in other equity securities with readily determinable fair values (publicly traded securities) of $397 million and $480 million as of June 30, 2023 and December 31, 2022, respectively, which are included in Other noncurrent assets in the Condensed Consolidated Balance Sheets. During the three months ended June 30, 2023 and 2022, net unrealized gains and losses on these publicly traded securities were a gain of $3 million and a loss of $106 million, respectively. During the six months ended June 30, 2023 and 2022, net unrealized gains and losses on these publicly traded securities were a net gain of $8 million and a net loss of $276 million, respectively. Realized gains and losses on sales of publicly traded securities for the three and six months ended June 30, 2023 and 2022, were not material. We held investments of $291 million and $233 million in equity securities without readily determinable fair values as of June 30, 2023 and December 31, 2022, respectively, which are included in Other noncurrent assets in the Condensed Consolidated Balance Sheets. During the three and six months ended June 30, 2023 and 2022, upward and downward adjustments on these securities were not material. Adjustments were based on observable price transactions. Equity method investments Neumora Therapeutics, Inc. On September 30, 2021, we acquired an approximately 25.9% ownership interest in Neumora, a privately held company, for $257 million, which is included in Other noncurrent assets in the Condensed Consolidated Balance Sheets, in exchange for a $100 million cash payment and $157 million in noncash consideration primarily related to future services. Although our equity investment provides us with the ability to exercise significant influence over Neumora, we have elected the fair value option to account for our equity investment. Under the fair value option, changes in the fair value of the investment are recognized through earnings in Other (expense) income, net, in our Condensed Consolidated Statements of Income each reporting period. We believe the fair value option best reflects the economics of the underlying transaction. As of June 30, 2023 and December 31, 2022, our ownership interest in Neumora was approximately 24.5% and 24.9%, respectively, and the fair values of our investment were $316 million and $335 million, respectively. During the three months ended June 30, 2023 and 2022, we recognized a gain of $28 million and a loss of $39 million, respectively, and during the six months ended June 30, 2023 and 2022, we recognized losses of $19 million and $89 million, respectively. For information on determination of fair values, see Note 12, Fair value measurement. Limited partnerships We held limited partnership investments of $226 million and $249 million as of June 30, 2023 and December 31, 2022, respectively, which are included in Other noncurrent assets in the Condensed Consolidated Balance Sheets. These investments, primarily investment funds of early-stage biotechnology companies, are accounted for by using the equity method of accounting and are measured by using our proportionate share of the net asset values of the underlying investments held by the limited partnerships as a practical expedient. These investments are typically redeemable only through distributions upon liquidation of the underlying assets. As of June 30, 2023, unfunded additional commitments to be made for these investments during the next several years amounted to $157 million. For the three months ended June 30, 2023 and 2022, net unrealized losses from our limited partnership investments were $29 million and $60 million, respectively. For the six months ended June 30, 2023 and 2022, net unrealized losses from our limited partnership investments were $9 million and $220 million, respectively.

Debt issuances and acquisition-related financing During the three months ended March 31, 2023, in connection with the proposed acquisition of Horizon (see Note 3, Acquisitions and divestitures —Proposed acquisition of Horizon Therapeutics plc ), we issued the following series of notes (in millions): Principal Amount 5.25% 2025 Notes $ 2,000 5.507% 2026 Notes 1,500 5.15% 2028 Notes 3,750 5.25% 2030 Notes 2,750 5.25% 2033 Notes 4,250 5.60% 2043 Notes 2,750 5.65% 2053 Notes 4,250 5.75% 2063 Notes 2,750 Total $ 24,000 If consummation of the proposed acquisition of Horizon does not occur on or before the later of (i) January 31, 2024, or such later date to which the agreement to acquire Horizon (Transaction Agreement) may be extended in accordance with its terms, (ii) the Transaction Agreement is terminated, or (iii) we otherwise notify the trustee of the notes that consummation of the acquisition will not be pursued, we will be required to redeem each series of notes, other than the 5.75% 2063 Notes, at a price equal to 101% of the principal amount of the notes plus accrued and unpaid interest. In the event of a change-in-control triggering event, as defined by the terms of the notes, we may be required to purchase all or a portion of these notes at a price equal to 101% of the principal amount of the notes plus accrued and unpaid interest. In addition, these notes may be redeemed at any time at our option, in whole or in part, at the principal amount of the notes being redeemed plus accrued and unpaid interest and a make-whole amount, which are defined by the terms of the notes. Except with respect to the 5.25% 2025 Notes, the notes may be redeemed without payment of make-whole amounts if redemption occurs during a specified period of time immediately prior to the maturing of the notes. Such time periods range from two months to six months prior to maturity, except for the 5.507% 2026 Notes, which may be redeemed without payment of the make-whole amount if redemption occurs after two years prior to maturity. In December 2022, in connection with the proposed acquisition of Horizon, we entered into a bridge credit agreement, which provided for borrowings with an aggregate principal amount of $24.5 billion as of December 31, 2022. Subsequent to our March 2023 debt issuance described above, we terminated the bridge credit agreement. Accordingly, during the three months ended March 31, 2023, we recognized $98 million of financing cost associated with the bridge credit agreement, primarily in Other (expense) income, net, in the Condensed Consolidated Statements of Income. Also in connection with the proposed acquisition of Horizon, we entered into a $4.0 billion term loan credit agreement in December 2022. No amounts under this agreement were outstanding as of June 30, 2023 and December 31, 2022. Debt extinguishment During the three months ended March 31, 2023, we repurchased portions of the 2.00% 2032 Notes, 3.15% 2040 Notes, 2.80% 2041 Notes, 3.375% 2050 Notes, 3.00% 2052 Notes, 4.20% 2052 Notes and 4.40% 2062 Notes for an aggregate cost of $420 million, which resulted in the recognition of a $113 million gain on extinguishment of debt recorded in Other (expense) income, net, in the Condensed Consolidated Statements of Income. Debt repayments During the three months ended March 31, 2023, we repaid the CHF700 million aggregate principal amount ($704 million upon settlement of the related cross-currency swap) of the 0.41% 2023 Swiss franc Bonds. Shelf registration statement and other facilities In February 2023, we filed a shelf registration statement with the SEC that allows us to issue unspecified amounts of debt securities; common stock; preferred stock; warrants to purchase debt securities, common stock, preferred stock or depositary shares; rights to purchase common stock or preferred stock; securities purchase contracts; securities purchase units; and depositary shares. Under this shelf registration statement, all of the securities available for issuance may be offered from time to time, with terms to be determined at the time of issuance. This shelf registration statement expires in February 2026. During the three months ended March 31, 2023, we amended and restated our syndicated, unsecured, revolving credit agreement, under which we may borrow up to $4.0 billion (increased from $2.5 billion prior to the amendment) for general corporate purposes, including as a liquidity backstop for our commercial paper program. The commitments under the revolving credit agreement may be increased by up to $1.25 billion with the agreement of the banks (increased from $750 million prior to the amendment). Each bank that is a party to the agreement has an initial commitment term of five years. This term may be extended for up to two additional one-year periods with the agreement of the banks. Annual commitment fees for this agreement are 0.09% of the unused portion of the facility based on our current credit rating. Generally, we would be charged interest for any amounts borrowed under this facility, based on our current credit rating, at (i) SOFR plus 1.01% or (ii) the highest of (A) the administrative agent bank base commercial lending rate, (B) the overnight federal funds rate plus 0.50% or (C) one-month SOFR plus 1.1%. As of June 30, 2023 and December 31, 2022, no amounts were outstanding under this facility.

Fair Value Disclosures [Abstract]
Fair value measurement	Fair value measurement To estimate the fair value of our financial assets and liabilities, we use valuation approaches within a hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing an asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing an asset or liability and are developed based on the best information available in the circumstances. The fair value hierarchy is divided into three levels based on the sources of inputs as follows: Level 1 — Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access Level 2 — Valuations for which all significant inputs are observable either directly or indirectly—other than Level 1 inputs Level 3 — Valuations based on inputs that are unobservable and significant to the overall fair value measurement The availability of observable inputs can vary among different types of financial assets and liabilities. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, inputs used for measuring fair value may fall into different levels of the fair value hierarchy. In such cases, for financial statement disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is categorized is based on the lowest level of input used that is significant to the overall fair value measurement. The fair values of each major class of the Company’s financial assets and liabilities measured at fair value on a recurring basis were as follows (in millions): Quoted prices Significant Significant Fair value measurement as of June 30, 2023, using: Total Assets: Available-for-sale securities: U.S. Treasury bills $ — $ — $ — $ — Money market mutual funds 33,618 — — 33,618 Other investments — 137 — 137 Equity securities Derivatives: 3,775 — 316 4,091 Foreign currency forward contracts — 251 — 251 Cross-currency swap contracts — — — — Total assets $ 37,393 $ 388 $ 316 $ 38,097 Liabilities: Derivatives: Foreign currency forward contracts $ — $ 83 $ — $ 83 Cross-currency swap contracts — 493 — 493 Interest rate swap contracts — 735 — 735 Forward interest rate contracts — — — — Contingent consideration obligations — — 248 248 Total liabilities $ — $ 1,311 $ 248 $ 1,559 Quoted prices Significant Significant Fair value measurement as of December 31, 2022, using: Total Assets: Available-for-sale securities: U.S. Treasury bills $ 1,676 $ — $ — $ 1,676 Money market mutual funds 2,659 — — 2,659 Other investments — 130 — 130 Equity securities 480 — 335 815 Derivatives: Foreign currency forward contracts — 287 — 287 Cross-currency swap contracts — 54 — 54 Total assets $ 4,815 $ 471 $ 335 $ 5,621 Liabilities: Derivatives: Foreign currency forward contracts $ — $ 76 $ — $ 76 Cross-currency swap contracts — 541 — 541 Interest rate swap contracts — 776 — 776 Forward interest rate contracts — 5 — 5 Contingent consideration obligations — — 270 270 Total liabilities $ — $ 1,398 $ 270 $ 1,668 Interest-bearing and equity securities The fair values of our U.S. Treasury securities, money market mutual funds and equity investments in publicly traded securities, including our equity investment in BeiGene as of June 30, 2023, are based on quoted market prices in active markets, with no valuation adjustment. Other investments consist of interest-bearing deposits that are valued at amortized cost, which approximates fair value given their near-term maturity. The fair values of equity securities without readily determinable fair values are initially valued at the transaction prices and subsequently valued based on a combination of observable price transactions when available, market performance and publicly available market information for similar companies that have actively traded equity securities. See Note 7, Investments— Neumora Therapeutics, Inc. As of the first quarter of 2023, we no longer account for our equity investment in BeiGene under the equity method of accounting. As of December 31, 2022, the fair value and carrying value were $4.2 billion and $2.2 billion, respectively. The fair value of our investment in BeiGene was estimated by using Level 1 inputs. See Note 7, Investments— BeiGene, Ltd. Derivatives All of our foreign currency forward contracts, cross-currency swap contracts and interest rate swap contracts are with counterparties that have minimum credit ratings of A– or equivalent by S&P, Moody’s or Fitch. We estimate the fair values of these contracts by taking into consideration valuations obtained from a third-party valuation service that uses an income-based industry-standard valuation model for which all significant inputs are observable either directly or indirectly. These inputs, as applicable, include foreign currency exchange rates, LIBOR, SOFR, swap rates, obligor credit default swap rates and cross-currency basis swap spreads. Certain inputs, when applicable, are at commonly quoted intervals. Starting in the third quarter of 2023, terms under our existing derivative contracts will reference the SOFR benchmark consistent with the ISDA protocol. See Note 13, Derivative instruments. Contingent consideration obligations As a result of our business acquisitions, we have incurred contingent consideration obligations as discussed below. The contingent consideration obligations are recorded at their fair values by using probability-adjusted discounted cash flows, and we revalue these obligations each reporting period until the related contingencies have been resolved. The fair value measurements of these obligations are based on significant unobservable inputs related to licensing rights and product candidates acquired in business combinations, and they are reviewed quarterly by management in our R&D and commercial sales organizations. The inputs include, as applicable, estimated probabilities and the timing of achieving specified development, regulatory and commercial milestones as well as estimated annual sales. Significant changes that increase or decrease the probabilities of achieving the related development, regulatory and commercial events or that shorten or lengthen the time required to achieve such events or that increase or decrease estimated annual sales would result in corresponding increases or decreases in the fair values of the obligations, as applicable. Changes in the fair values of contingent consideration obligations are recognized in Other operating expenses in the Condensed Consolidated Statements of Income. Changes in the carrying amounts of contingent consideration obligations were as follows (in millions): Three months ended Six months ended 2023 2022 2023 2022 Beginning balance $ 273 $ 330 $ 270 $ 342 Payments (2) (1) (4) (3) Net changes in valuations (23) (19) (18) (29) Ending balance $ 248 $ 310 $ 248 $ 310 As of June 30, 2023 and December 31, 2022, our contingent consideration obligations are primarily the result of our acquisition of Teneobio, in October 2021, which obligates us to pay the former shareholders up to $1.6 billion upon achieving separate development and regulatory milestones with regard to various R&D programs. Summary of the fair values of other financial instruments Cash equivalents The fair values of cash equivalents approximate their carrying values due to the short-term nature of such financial instruments. Borrowings We estimated the fair values of our borrowings by using Level 2 inputs. As of June 30, 2023 and December 31, 2022, the aggregate fair values of our borrowings were $59.1 billion and $35.0 billion, respectively, and the carrying values were $61.5 billion and $38.9 billion, respectively. During the six months ended June 30, 2023 and 2022, there were no transfers of assets or liabilities between fair value measurement levels, and there were no material remeasurements to the fair values of assets and liabilities that are not measured at fair value on a recurring basis.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative instruments	Derivative instruments The Company is exposed to foreign currency exchange rate and interest rate risks related to its business operations. To reduce our risks related to such exposures, we use or have used certain derivative instruments, including foreign currency forward, foreign currency option, cross-currency swap, forward interest rate and interest rate swap contracts. We have designated certain of our derivatives as cash flow and fair value hedges; we also have derivatives not designated as hedges. We do not use derivatives for speculative-trading purposes. Cash flow hedges We are exposed to possible changes in the values of certain anticipated foreign currency cash flows resulting from changes in foreign currency exchange rates primarily associated with our euro-denominated international product sales. The foreign currency exchange rate fluctuation exposure associated with cash inflows from our international product sales is partially offset by corresponding cash outflows from our international operating expenses. To further reduce our exposure, we enter into foreign currency forward contracts to hedge a portion of our projected international product sales up to a maximum of three years into the future; and at any given point in time, a higher percentage of nearer-term projected product sales is being hedged than in successive periods. As of June 30, 2023 and December 31, 2022, we had outstanding foreign currency forward contracts with aggregate notional amounts of $6.1 billion and $6.0 billion, respectively. We have designated these foreign currency forward contracts, which are primarily euro based, as cash flow hedges. Accordingly, we report the unrealized gains and losses on these contracts in AOCI in the Condensed Consolidated Balance Sheets, and we reclassify them to Product sales in the Condensed Consolidated Statements of Income in the same periods during which the hedged transactions affect earnings. To hedge our exposure to foreign currency exchange rate risk associated with certain of our long-term debt denominated in foreign currencies, we enter into cross-currency swap contracts. Under the terms of such contracts, we paid euros, pounds sterling and Swiss francs and received U.S. dollars for the notional amounts at the inception of the contracts; and based on these notional amounts, we exchange interest payments at fixed rates over the lives of the contracts by paying U.S. dollars and receiving euros, pounds sterling and Swiss francs. In addition, we will pay U.S. dollars to and receive euros, pounds sterling and Swiss francs from the counterparties at the maturities of the contracts for these same notional amounts. The terms of these contracts correspond to the related hedged debt, thereby effectively converting the interest payments and principal repayment on the debt from euros, pounds sterling and Swiss francs to U.S. dollars. We have designated these cross-currency swap contracts as cash flow hedges. Accordingly, the unrealized gains and losses on these contracts are reported in AOCI in the Condensed Consolidated Balance Sheets and reclassified to Other (expense) income, net, in the Condensed Consolidated Statements of Income in the same periods during which the hedged debt affects earnings. The notional amounts and interest rates of our cross-currency swaps as of June 30, 2023, were as follows (notional amounts in millions): Foreign currency U.S. dollars Hedged notes Notional amounts Interest rates Notional amounts Interest rates 2.00% 2026 euro Notes € 750 2.0 % $ 833 3.9 % 5.50% 2026 pound sterling Notes £ 475 5.5 % $ 747 6.0 % 4.00% 2029 pound sterling Notes £ 700 4.0 % $ 1,111 4.6 % In connection with the anticipated issuance of long-term fixed-rate debt, we occasionally enter into forward interest rate contracts in order to hedge the variability in cash flows due to changes in the applicable U.S. Treasury rate between the time we enter into these contracts and the time the related debt is issued. Gains and losses on forward interest rate contracts, which are designated as cash flow hedges, are recognized in AOCI i n the Condensed Consolidated Balance Sheets and are amortized into Interest expense, net, in the Condensed Consolidated Statements of Income over the lives of the associated debt issuances. Amounts recognized in connection with forward interest rate contracts during the six months ended June 30, 2023, and amounts expected to be recognized during the subsequent 12 months are not material. Gains and losses recognized in AOCI for our derivative instruments designated as cash flow hedges were as follows (in millions): Three months ended Six months ended Derivatives in cash flow hedging relationships 2023 2022 2023 2022 Foreign currency forward contracts $ 24 $ 252 $ 24 $ 330 Cross-currency swap contracts 26 (185) (14) (207) Forward interest rate contracts — — (31) — Total unrealized gains (losses) $ 50 $ 67 $ (21) $ 123 Fair value hedges To achieve a desired mix of fixed-rate and floating-rate debt, we entered into interest rate swap contracts that qualified for and were designated as fair value hedges. These interest rate swap contracts effectively convert fixed-rate coupons to floating-rate coupons over the terms of the related hedge contracts. As of both June 30, 2023 and December 31, 2022, we had interest rate swap contracts with aggregate notional amounts of $6.7 billion that hedge certain portions of our long-term debt issuances. For interest rate swap contracts that qualify for and are designated as fair value hedges, we recognize in Interest expense, net, in the Condensed Consolidated Statements of Income the unrealized gain or loss on the derivative resulting from the change in fair value during the period, as well as the offsetting unrealized loss or gain of the hedged item resulting from the change in fair value during the period attributable to the hedged risk. If a hedging relationship involving an interest rate swap contract is terminated, the gain or loss realized on contract termination is recorded as an adjustment to the carrying value of the debt and amortized into Interest expense, net, over the remaining life of the previously hedged debt. The hedged liabilities and related cumulative-basis adjustments for fair value hedges of those liabilities were recorded in the Condensed Consolidated Balance Sheets as follows (in millions): Carrying amounts of hedged liabilities (1) Cumulative amounts of fair value hedging adjustments related to the carrying amounts of the hedged liabilities (2) Condensed Consolidated Balance Sheets locations June 30, 2023 December 31, 2022 June 30, 2023 December 31, 2022 Current portion of long-term debt $ 1,416 $ 82 $ 16 $ 82 Long-term debt $ 4,688 $ 6,017 $ (452) $ (519) ____________ (1) Current portion of long-term debt includes $80 million and $82 million of carrying value with discontinued hedging relationships as of June 30, 2023 and December 31, 2022, respectively. Long-term debt includes $318 million and $357 million of carrying value with discontinued hedging relationships as of June 30, 2023 and December 31, 2022, respectively. (2) Current portion of long-term debt includes $80 million and $82 million of hedging adjustments on discontinued hedging relationships as of June 30, 2023 and December 31, 2022, respectively. Long-term debt includes $218 million and $257 million of hedging adjustments on discontinued hedging relationships as of June 30, 2023 and December 31, 2022, respectively. Impact of hedging transactions The following tables summarize the amounts recorded in income and expense line items and the effects thereon from fair value and cash flow hedging, including discontinued hedging relationships (in millions): Three months ended June 30, 2023 Six months ended June 30, 2023 Product sales Other (expense) income, net Interest expense, net Product sales Other (expense) income, net Interest expense, net Total amounts recorded in income and (expense) line items presented in the Condensed Consolidated Statements of Income $ 6,683 $ (318) $ (752) $ 12,529 $ 1,746 $ (1,295) The effects of cash flow and fair value hedging: Gains on cash flow hedging relationships reclassified out of AOCI: Foreign currency forward contracts $ 36 $ — $ — $ 88 $ — $ — Cross-currency swap contracts $ — $ 51 $ — $ — $ 29 $ — Gains (losses) on fair value hedging relationships—interest rate swap agreements: Hedged items (1) $ — $ — $ 93 $ — $ — $ 5 Derivatives designated as hedging instruments $ — $ — $ (72) $ — $ — $ 42 Three months ended June 30, 2022 Six months ended June 30, 2022 Product sales Other (expense) income, net Interest expense, net Product sales Other (expense) income, net Interest expense, net Total amounts recorded in income and (expense) line items presented in the Condensed Consolidated Statements of Income $ 6,281 $ (317) $ (328) $ 12,012 $ (847) $ (623) The effects of cash flow and fair value hedging: Gains (losses) on cash flow hedging relationships reclassified out of AOCI: Foreign currency forward contracts $ 53 $ — $ — $ 80 $ — $ — Cross-currency swap contracts $ — $ (185) $ — $ — $ (263) $ — Gains (losses) on fair value hedging relationships—interest rate swap agreements: Hedged items (1) $ — $ — $ 157 $ — $ — $ 494 Derivatives designated as hedging instruments $ — $ — $ (135) $ — $ — $ (450) __________ (1) Gains on hedged items do not exactly offset losses on the related designated hedging instruments due to amortization of the cumulative amounts of fair value hedging adjustments included in the carrying amount of the hedged debt for discontinued hedging relationships and the recognition of gains on terminated hedges when the corresponding hedged item was paid down in the period. No portions of our cash flow hedge contracts were excluded from the assessment of hedge effectiveness. As of June 30, 2023, we expected to reclassify $108 million of net gains on our foreign currency and cross-currency swap contracts out of AOCI and into earnings during the next 12 months. Derivatives not designated as hedges To reduce our exposure to foreign currency fluctuations in certain assets and liabilities denominated in foreign currencies, we enter into foreign currency forward contracts that are not designated as hedging transactions. Most of these exposures are hedged on a month-to-month basis. As of June 30, 2023 and December 31, 2022, the total notional amounts of these foreign currency forward contracts were $557 million and $517 million, respectively. Gains and losses recognized in earnings for our derivative instruments not designated as hedging instruments were not material for the three and six months ended June 30, 2023 and 2022. Fair values of derivatives The fair values of derivatives included in the Condensed Consolidated Balance Sheets were as follows (in millions): Derivative assets Derivative liabilities June 30, 2023 Condensed Consolidated Fair values Condensed Consolidated Fair values Derivatives designated as hedging instruments: Foreign currency forward contracts Other current assets/ Other noncurrent assets $ 251 Accrued liabilities/ Other noncurrent liabilities $ 83 Cross-currency swap contracts Other current assets/ Other noncurrent assets — Accrued liabilities/ Other noncurrent liabilities 493 Interest rate swap contracts Other current assets/ Other noncurrent assets — Accrued liabilities/ Other noncurrent liabilities 735 Forward interest rate contracts Other current assets/ Other noncurrent assets — Accrued liabilities/ Other noncurrent liabilities — Total derivatives designated as hedging instruments 251 1,311 Total derivatives $ 251 $ 1,311 Derivative assets Derivative liabilities December 31, 2022 Condensed Consolidated Fair values Condensed Consolidated Fair values Derivatives designated as hedging instruments: Foreign currency forward contracts Other current assets/ Other noncurrent assets $ 287 Accrued liabilities/ Other noncurrent liabilities $ 76 Cross-currency swap contracts Other current assets/ Other noncurrent assets 54 Accrued liabilities/ Other noncurrent liabilities 541 Interest rate swap contracts Other current assets/ Other noncurrent assets — Accrued liabilities/ Other noncurrent liabilities 776 Forward interest rate contracts Other current assets/ Other noncurrent assets — Accrued liabilities/ Other noncurrent liabilities 5 Total derivatives designated as hedging instruments 341 1,398 Total derivatives $ 341 $ 1,398 For additional information, see Note 12, Fair value measurement. Our derivative contracts that were in liability positions as of June 30, 2023, contain certain credit-risk-related contingent provisions that would be triggered if (i) we were to undergo a change-in-control and (ii) our or the surviving entity’s creditworthiness deteriorates, which is generally defined as having either a credit rating that is below investment grade or a materially weaker creditworthiness after the change-in-control. If these events were to occur, the counterparties would have the right, but not the obligation, to close the contracts under early-termination provisions. In such circumstances, the counterparties could request immediate settlement of these contracts for amounts that approximate the then current fair values of the contracts. In addition, our derivative contracts are not subject to any type of master netting arrangement, and amounts due either to or from a counterparty under the contracts may be offset against other amounts due either to or from the same counterparty only if an event of default or termination, as defined, were to occur. The cash flow effects of our derivative contracts in the Condensed Consolidated Statements of Cash Flows are included in Net cash provided by operating activities, except for the settlement of notional amounts of cross-currency swaps, which are included in Net cash provided by (used in) financing activities.

Commitments and Contingencies Disclosure [Abstract]
Contingencies and commitments	Contingencies and commitments Contingencies In the ordinary course of business, we are involved in various legal proceedings, government investigations and other matters that are complex in nature and have outcomes that are difficult to predict. See our Annual Report on Form 10-K for the year ended December 31, 2022, Part I, Item 1A. Risk Factors— Our business may be affected by litigation and government investigations. We describe our legal proceedings and other matters that are significant or that we believe could become significant in this footnote; and in Note 19, Contingencies and commitments, to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2022; and in Note 14, Contingencies and commitments, to the condensed consolidated financial statements in our Quarterly Report on Form 10-Q for the period ended March 31, 2023. We record accruals for loss contingencies to the extent that we conclude it is probable that a liability has been incurred and the amount of the related loss can be reasonably estimated. We evaluate, on a quarterly basis, developments in legal proceedings and other matters that could cause an increase or decrease in the amount of the liability that has been accrued previously. Our legal proceedings involve various aspects of our business and a variety of claims, some of which present novel factual allegations and/or unique legal theories. In each of the matters described in this filing; and in Note 19, Contingencies and commitments, to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2022; and in Note 14, Contingencies and commitments, to the condensed consolidated financial statements in our Quarterly Report on Form 10-Q for the period ended March 31, 2023, in which we could incur a liability, our opponents seek an award of a not-yet-quantified amount of damages or an amount that is not material. In addition, a number of the matters pending against us are at very early stages of the legal process, which in complex proceedings of the sort we face often extend for several years. As a result, none of the matters described in this filing; and in Note 19, Contingencies and commitments, to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2022; and in Note 14, Contingencies and commitments, to the condensed consolidated financial statements in our Quarterly Report on Form 10-Q for the period ended March 31, 2023, in which we could incur a liability, have progressed sufficiently through discovery and/or the development of important factual information and legal issues to enable us to estimate a range of possible loss, if any, or such amounts are not material. While it is not possible to accurately predict or determine the eventual outcomes of these matters, an adverse determination in one or more of these matters currently pending could have a material adverse effect on our consolidated results of operations, financial position or cash flows. Certain recent developments concerning our legal proceedings and other matters are discussed below: Repatha Patent Litigation Amgen Inc., et al. v. Sanofi, et al. On May 18, 2023, the U.S. Supreme Court entered final judgment affirming the lower court’s decision invalidating claims 19 and 29 of U.S. Patent No. 8,829,165 and claim 7 of the U.S. Patent No. 8,859,741 as lacking an enabling disclosure of the invention claimed. Patent Disputes in the International Region On June 1, 2023, Amgen filed an action before the Unitary Patent Court against Sanofi-Aventis Deutschland GmbH, Sanofi-Aventis Groupe S.A., Sanofi Winthrop Industrie S.A. (collectively, Sanofi) and Regeneron Pharmaceuticals, Inc. alleging that the importation, marketing, sale and use of PRALUENT ® infringes European Patent 3,666,797 (the EP’797 Patent) seeking an injunction and damages for past infringement. On June 29, 2023, the Unitary Patent Court served us with an action filed by Sanofi before the Unitary Patent Court seeking revocation of Amgen’s EP’797 Patent. On July 20, 2023, Amgen filed objections to the admissibility of Sanofi’s revocation action before the Unitary Patent Court’s Central Division and Local Divisions on the grounds that Amgen’s infringement action was filed prior to Sanofi’s revocation action. On November 14, 2023, the Regional Court of Dusseldorf is scheduled to hear argument on Sanofi Biotechnology SAS’ lawsuit alleging that our marketing of Repatha infringes European Patent 2,756,004. The Munich Regional Court scheduled a hearing for February 28, 2024 on Sanofi’s action against Amgen in which Sanofi seeks damages arising from the provisional enforcement of an injunction against PRALUENT ® that was lifted after an October 29, 2020 ruling by the Technical Board of Appeal that broader claims in Amgen’s European Patent 2,215,125 encompassing PRALUENT ® were invalid. Prolia/XGEVA Biologics Price Competition and Innovation Act (BPCIA) Litigation Amgen Inc. et al. v. Sandoz Inc., et al. On May 1, 2023, Amgen Inc. and Amgen Manufacturing Limited filed a lawsuit in the U.S. District Court for the District of New Jersey (New Jersey District Court) against Sandoz Inc., Sandoz GmbH, Lek Pharmaceuticals d.d., Novartis Pharmaceutical Productions d.o.o., and Novartis AG (collectively, Defendants) based on the submission to the FDA of a Biologics License Application seeking approval to market and sell a biosimilar version of Amgen’s Prolia and XGEVA products. The complaint asserts infringement of the following 21 patents, which are listed in the FDA’s Purple Book for Amgen’s Prolia and XGEVA products: U.S. Patent Nos. 7,364,736; 7,928,205; 8,058,418; 9,012,178; 9,133,493; 9,228,168; 9,320,816; 9,328,134; 9,359,435; 9,481,901; 10,167,492; 10,513,723; 10,583,397; 10,822,630; 10,894,972; 11,077,404; 11,098,079; 11,130,980; 11,254,963; 11,299,760; and 11,434,514 (collectively, the Asserted Patents). Amgen seeks a judgment from the New Jersey District Court that Defendants have infringed or will infringe one or more claims of each of the Asserted Patents and based on that judgment, a permanent injunction prohibiting the commercial manufacture, use, offer to sell, or sale within the United States or importation into the United States of Defendants’ proposed denosumab biosimilar before expiration of each of the Asserted Patents found to infringe. Amgen also seeks monetary remedies for any past acts of infringement. On June 16, 2023, Amgen filed an amended and supplemental complaint to include additional information regarding the completion of the BPCIA information exchange after the filing of the original complaint. Sandoz Inc. responded to the amended and supplemental complaint on July 7, 2023, denying infringement and asserting counterclaims seeking a declaratory judgment that asserted patents are invalid and/or unenforceable. On July 21, 2023, the New Jersey District Court granted Amgen’s request for a briefing schedule to present and hear a motion to be filed by Amgen on or before September 1, 2023 seeking a preliminary injunction to prohibit patent infringement by Sandoz’s denosumab product until the court is able to reach judgment on the merits of Amgen’s lawsuit. On August 2, 2023, the New Jersey District Court scheduled a preliminary injunction hearing that will commence on October 30, 2023. ABP 654 (ustekinumab) Patent Litigation Janssen Biotech, Inc. v. Amgen Inc. On May 22, 2023, pursuant to a confidential settlement agreement, the parties filed a joint stipulation of dismissal with prejudice of the U.S. litigation. On May 23, 2023, the U.S. District Court for the District of Delaware (Delaware District Court) issued an order dismissing the U.S. litigation with prejudice. Janssen Biotech Inc. v. Amgen Technology (Ireland) Unlimited Company On May 22, 2023, pursuant to a confidential settlement agreement, the parties requested that the Irish proceedings be struck out and on the same day the Irish High Court issued an order striking out the proceedings and vacating all previous orders in those proceedings. Antitrust Class Action Sensipar Antitrust Class Actions On June 26, 2023, the U.S. Court of Appeals for the Third Circuit entered an order granting defendants’ (including Amgen’s) petition for interlocutory appeal and denying plaintiffs’ cross-petition. The questions certified are whether (1) the statute for interlocutory decisions authorizes a district court judge to certify for interlocutory appeal an order issued in the same case by a predecessor district court judge; and (2) the settlement of a patent infringement claim that involves the forgiveness of damages associated with that patent’s alleged infringement, on its own or combined with an acceleration clause, constitutes a reverse payment. On July 3, 2023, Amgen and Teva Pharmaceuticals USA, Inc. filed a notice of appeal. Regeneron Pharmaceuticals, Inc. Antitrust Action The Delaware District Court scheduled the trial to begin on November 12, 2024. U.S. Tax Litigation Amgen Inc. & Subsidiaries v. Commissioner of Internal Revenue See Note 5, Income taxes, for discussion of the IRS tax dispute and the Company’s petitions in the U.S. Tax Court. Shareholder Derivative Litigation On August 2, 2023, Leon Martin filed a derivative action, purportedly on behalf of Amgen, against Amgen, Robert Bradway, Peter Griffith and Amgen’s independent board members. The action was filed in the U.S. District Court for the Southern District of New York as related to the pending federal securities class action filed by Roofers Local No. 149 Pension Fund on March 13, 2023 (the Roofers securities class action). The complaint in this matter alleges claims for violations of the Securities Exchange Act of 1934, breach of fiduciary duty, aiding and abetting breach of fiduciary duty, unjust enrichment and waste of corporate assets. The factual allegations that form the basis for these claims are essentially the same as the allegations asserted in the Roofers securities class action regarding purportedly false and misleading statements and omissions made from July 29, 2020 through April 27, 2022 relating to Amgen’s tax liabilities, business and finances, and the adequacy and maintenance of its internal controls. FTC Litigation re the Proposed Horizon Therapeutics plc Acquisition On May 16, 2023, the FTC filed a complaint and motion for preliminary injunction in the U.S. District Court for the Northern District of Illinois (Northern Illinois District Court) seeking to enjoin Amgen’s proposed acquisition of Horizon. The FTC alleges that the deal would allow Amgen to leverage its portfolio of blockbuster drugs someday to entrench the monopoly positions of Horizon medications used to treat two serious conditions, thyroid eye disease and chronic refractory gout, if competitors eventually come to market. The preliminary injunction hearing in the case is set to begin on September 11, 2023. On June 1, 2023, Amgen, Horizon and the FTC submitted a stipulated proposed temporary restraining order (TRO) to the Northern Illinois District Court providing that Horizon and Amgen would not close the acquisition until the earlier of October 31, 2023 or the second business day after the Northern Illinois District Court rules on the FTC’s request for a preliminary injunction. On June 2, 2023, the Northern Illinois District Court issued an order granting the stipulated TRO. Amgen and Horizon filed their answer to the complaint on June 9, 2023. On June 22, 2023, an amended complaint was filed adding six states to the lawsuit, and on June 29, 2023, Amgen filed an answer and counterclaims to the amended complaint. On June 22, 2023, the FTC filed an administrative complaint before the FTC’s administrative judge, and on July 7, 2023 Amgen and Horizon filed an answer to the administrative complaint. The Transaction Agreement provides that Amgen will be required to pay Horizon a termination fee of $974.4 million if the Transaction Agreement is terminated under certain circumstances in which there was a failure to obtain regulatory approvals by December 12, 2023, as described in Amgen’s Form 8-K filed December 12, 2022, and in the Transaction Agreement filed therewith. One of those circumstances would likely arise if the above-described preliminary injunction hearing is not decided favorably to Amgen and Horizon.

Basis of presentation	Basis of presentation The financial information for the three and six months ended June 30, 2023 and 2022, is unaudited but includes all adjustments (consisting of only normal, recurring adjustments unless otherwise indicated), which Amgen considers necessary for a fair presentation of its condensed consolidated results of operations for those periods. Interim results are not necessarily indicative of results for the full fiscal year.

Principles of consolidation	Principles of consolidation The condensed consolidated financial statements include the accounts of Amgen as well as its majority-owned subsidiaries. In determining whether we are the primary beneficiary of a variable interest entity, we consider whether we have both the power to direct activities of the entity that most significantly impact the entity’s economic performance and the obligation to absorb losses of or the right to receive benefits from the entity that could potentially be significant to that entity. We do not have any significant interests in any variable interest entities of which we are the primary beneficiary. All material intercompany transactions and balances have been eliminated in consolidation.
Use of estimates	Use of estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results may differ from those estimates.
